Monsoons represent some of the most important weather phenomena and climate systems on Earth and the Asian monsoon is the largest and most intense such known on the planet today. Summer rainfall in Asia is critical to the development and sustenance of human civilizations across the continent. The Asian monsoon is often linked to the regional tectonics and the summer rains in turn feeds back on the evolution of the solid Earth. In this seminar series we bring together some of the most active researchers looking at how the intensity of the Asian, Indonesian, Australian and South American monsoons have changed over long periods of geological time, even preceding the initial collision of India with Asia. We also consider changes on shorter, millennial timescales in the recent geological past, when variations are more controlled by orbital and solar processes.

Once a week through 2021, we will have an online seminar through Zoom, which will be recorded and archived on YouTube, profiling active research in this discipline. The seminar series highlights the recent developments following a sustained campaign of scientific ocean drilling offshore, but also the newest developments within continental basins and lakes spanning the global monsoon domain. The series of talks is supported by the Asia Oceania Geoscience Society (https://www.asiaoceania.org/society/index.asp).

The seminar series is open to all those interested in the geology of the monsoon. Please feel free to tell your students, colleagues, advisors and all interested parties to attend. We focus on atmospheric, oceanographic and continental aspects of this global phenomenon on a temporal dimension that goes beyond historical direct measurement ranges.

The seminars are planned to be once a week alternately favoring those residing in the western hemisphere and the following week those based in the Asia-Pacific region in order to allow both communities to attend at reasonable times and ask questions in person. Nonetheless, everyone will be able to access the recorded lectures online as they will be stored on the dedicated “Monsoon Seminar Series” channel on YouTube. Below we provide the schedule as it now stands and this list of the lectures will be updated as and when changes are necessary. You can also check on the schedule at the following address


A link to the zoom meeting is available at the end of this message and will be provided again prior to the start of the lectures on January 13, 2021.

At the end of the spring and later fall sessions we will host an online discussion forum for greater discussion of the major questions that is not possible or practical after each of the weekly lectures.
